Multilingual simultaneous interpretation using a distributed ledger

ABSTRACT

Methods, apparatuses, and computer program products for multilingual simultaneous interpretation using a distributed ledger are disclosed. A multilingual interpretation server determines that a new word has been added to a first language node, the first language node corresponding to a first language, and broadcasts, to a plurality of other language nodes, a request to interpret the new word, wherein each of the plurality of other language nodes corresponds to a different language. Each of the plurality of language nodes interprets the new word into a particular language and adds the new word and one or more interpretations of the new word to an entry in a dictionary ledger. A multilingual interpretation service provides simultaneous multilingual translations of from a source language to a plurality of target languages using the shared distributed dictionary ledger. A multilingual interpretation client is provided for accessing services provided by the multilingual interpretation service.

BACKGROUND Field of the Invention

The field of the invention is data processing, or, more specifically, methods, apparatus, and products for multilingual simultaneous interpretation using a distributed ledger.

Description of Related Art

The development of the EDVAC computer system of 1948 is often cited as the beginning of the computer era. Since that time, computer systems have evolved into extremely complicated devices. Today's computers are much more sophisticated than early systems such as the EDVAC. Computer systems typically include a combination of hardware and software components, application programs, operating systems, processors, buses, memory, input/output devices, and so on. As advances in semiconductor processing and computer architecture push the performance of the computer higher and higher, more sophisticated computer software has evolved to take advantage of the higher performance of the hardware, resulting in computer systems today that are much more powerful than just a few years ago.

Multilingual simultaneous interpretation is a useful tool, for example, at events or conferences where the participants and audience members speak a wide variety of different languages. Increasingly, computer systems are used in machine interpretation and machine translation for multilingual simultaneous interpretation. However, there are an estimated 5,000 to 7,000 languages spoken today, and each year new words are added to those languages. For example, in January of 2018 the Oxford English Dictionary announced that it had added over 1,100 new words, senses, and subentries. By March of 2018, it had added more than 700 additional words, senses, and subentries.

It is difficult to manage large machine interpretation and machine translation dictionaries in different languages for handling newly added words to the vocabulary. Moreover, the qualities of machine interpretation and machine translation in different languages may be different due to, for example, the use of inconsistent dictionaries in different languages. Furthermore, it is difficult to synchronize machine interpretation and machine translation dictionaries with the original source language, and to know whether newly added words can be properly interpreted or translated.

SUMMARY

Embodiments in accordance with the present invention are directed to synchronizing and managing interpretation dictionaries in different languages for handling newly added words and making each newly added word available to all languages in an ecosystem of different languages. Embodiments in accordance with the present invention are also directed an interpretation service for providing intelligent simultaneous translations of a source language into multiple different target languages.

DETAILED DESCRIPTION

Exemplary methods, apparatus, and products for multilingual simultaneous interpretation using a distributed ledger in accordance with the present invention are described with reference to the accompanying drawings, beginning with FIG. 1. FIG. 1 sets forth a network diagram of a system configured for multilingual simultaneous interpretation using a distributed ledger according to embodiments of the present invention. The system (100) of FIG. 1 includes multilingual interpretation server (101) and the multilingual interpretation client (103). The multilingual interpretation server (101) provides a multilingual interpretation service to the multilingual interpretation client (103) through the network (110), for example, in a Software as a Service (SaaS) delivery model.

The multilingual interpretation server (101) receives a multilingual interpretation request that includes a one or more words (i.e., a string) in a source language and a plurality of different target languages. The multilingual interpretation server (101) may provide an application programming interface (API) for accepting multilingual interpretation requests from the multilingual interpretation client (103). For example, a header of a request may indicate source language and one or more target languages, and the payload of the request may include a string to be translated into the target languages from the source language. The multilingual interpretation server (101) simultaneously interprets the string into the target languages and provides a reply including the multilingual interpretation in a reply to the multilingual interpretation client (103).

The multilingual interpretation client (103) formats a multilingual interpretation request through the API provided by multilingual interpretation server (101) and receives the multilingual interpretation from the multilingual interpretation server (101) for distribution to an audience. In the particular example where a speaker addresses audience members of different native languages, the multilingual interpretation client (103) detects the language of the speaker (i.e., the source language) and a word or phrase spoken by the speaker via a microphone (104), converts the speaker's speech to text, identifies different target languages into which the word or phases is to be interpreted, and transmits the string in the source language and the identified target languages to the multilingual interpretation server (101) for interpretation. Continuing this example, the multilingual interpretation client (103) receives the multilingual interpretation reply from the multilingual interpretation server (101), determines the native language for each audience member, and delivers the interpretation in that native language to a headset (108, 109) of each audience member by converting the text of the interpretation into speech.

FIG. 1 illustrates, by way of example and not limitation, that a speaker says the word “dog” in English into the microphone (104), which is converted to text by a speech-to-text generator (not shown) of the multilingual interpretation client (103). The multilingual interpretation client (103) formats a multilingual interpretation request in which the source language is identified as English, a plurality of target languages (e.g., Spanish, French) are identified, and the word “dog” is included as a payload of the request. The multilingual interpretation request is transmitted to the multilingual interpretation server (101), which replies with the multilingual interpretation of “dog” into the target languages. The multilingual interpretation client (103) then identifies that an audience member speaks Spanish and another audience member speaks French, and respectively delivers to a headset (108, 109) each audience member the interpretation of “dog” in their respective native languages, for example, via a text-to-speech generator (not shown).

The arrangement of servers and other devices making up the exemplary system illustrated in FIG. 1 are for explanation, not for limitation. Data processing systems useful according to various embodiments of the present invention may include additional servers, routers, other devices, and peer-to-peer architectures, not shown in FIG. 1, as will occur to those of skill in the art. Networks in such data processing systems may support many data communications protocols, including for example TCP (Transmission Control Protocol), IP (Internet Protocol), HTTP (HyperText Transfer Protocol), WAP (Wireless Access Protocol), HDTP (Handheld Device Transport Protocol), and others as will occur to those of skill in the art. Various embodiments of the present invention may be implemented on a variety of hardware platforms in addition to those illustrated in FIG. 1.

Multilingual simultaneous interpretation using a distributed ledger in accordance with the present invention is generally implemented with computers, that is, with automated computing machinery. In the system of FIG. 1, for example, all the multilingual interpretation server (101), and the multilingual interpretation client (103) are implemented to some extent at least as computers. For further explanation, therefore, FIG. 2 sets forth a block diagram of automated computing machinery comprising an exemplary computer (152) configured for multilingual simultaneous interpretation using a distributed ledger according to embodiments of the present invention. The computer (152) of FIG. 2 includes at least one computer processor (156) or ‘CPU’ as well as random access memory (168) (‘RAM’) which is connected through a high speed memory bus (166) and bus adapter (158) to processor (156) and to other components of the computer (152).

Stored in RAM (168) is a multilingual interpretation manager (MIM) (310), a module of computer program instructions improved for multilingual simultaneous interpretation using a distributed ledger according to embodiments of the present invention, that includes a multilingual interpretation synchronization (MIS) service (330), a module of computer program instructions for synchronizing interpretations of words among multiple different languages, a multilingual simultaneous interpretation (MSI) service (350), a module of computer program instructions for simultaneously translating a word in source language into multiple different target languages, and an administration module (340), a module of computer program instructions for managing settings of the MIM (310). Also stored in RAM (168) is a local instance of a distributed dictionary ledger (307).

Also stored in RAM (168) is an operating system (154). Operating systems useful in computers configured for multilingual simultaneous interpretation using a distributed ledger according to embodiments of the present invention include UNIX™, Linux™, Microsoft XP™, AIX™, IBM's i5/OS™, and others as will occur to those of skill in the art. The operating system (154), the MIM (310), the MIS service (330), the MSI service (350), the administration module (340) and the distributed dictionary ledger (307) in the example of FIG. 2 are shown in RAM (168), but many components of such software typically are stored in non-volatile memory also, such as, for example, on a disk drive (170).

The computer (152) of FIG. 2 includes disk drive adapter (172) coupled through expansion bus (160) and bus adapter (158) to processor (156) and other components of the computer (152). Disk drive adapter (172) connects non-volatile data storage to the computer (152) in the form of disk drive (170). Disk drive adapters useful in computers configured for multilingual simultaneous interpretation using a distributed ledger according to embodiments of the present invention include Integrated Drive Electronics (‘IDE’) adapters, Small Computer System Interface (‘SCSI’) adapters, and others as will occur to those of skill in the art. Non-volatile computer memory also may be implemented for as an optical disk drive, electrically erasable programmable read-only memory (so-called ‘EEPROM’ or ‘Flash’ memory), RAM drives, and so on, as will occur to those of skill in the art.

The example computer (152) of FIG. 2 includes one or more input/output (‘I/O’) adapters (178). I/O adapters implement user-oriented input/output through, for example, software drivers and computer hardware for controlling output to display devices such as computer display screens, as well as user input from user input devices (181) such as keyboards and mice. The example computer (152) of FIG. 2 includes a video adapter (209), which is an example of an I/O adapter specially designed for graphic output to a display device (180) such as a display screen or computer monitor. Video adapter (209) is connected to processor (156) through a high speed video bus (164), bus adapter (158), and the front side bus (162), which is also a high speed bus.

The exemplary computer (152) of FIG. 2 includes a communications adapter (167) for data communications with other computers (182) and for data communications with a data communications network (110). Such data communications may be carried out serially through RS-232 connections, through external buses such as a Universal Serial Bus (‘USB’), through data communications networks such as IP data communications networks, and in other ways as will occur to those of skill in the art. Communications adapters implement the hardware level of data communications through which one computer sends data communications to another computer, directly or through a data communications network. Examples of communications adapters useful in computers configured for multilingual simultaneous interpretation using a distributed ledger according to embodiments of the present invention include modems for wired dial-up communications, Ethernet (IEEE 802.3) adapters for wired data communications, and 802.11 adapters for wireless data communications.

For further explanation, FIG. 3 sets forth a block diagram of an exemplary multilingual interpretation management system configured for multilingual simultaneous interpretation using a distributed ledger according to embodiments of the present invention that includes a multilingual interpretation manager (MIM) (310).

In the example of FIG. 3, the MIM (310) includes a includes a multilingual interpretation synchronization (MIS) service (330) for synchronizing interpretations of words among multiple different languages and a multilingual simultaneous interpretation (MSI) service (350) for simultaneously translating a word in source language into multiple different target languages. The MIM (310) may be a centralized server, such as the exemplary computer of FIG. 2, or may be distributed among multiple servers. Accordingly, the MIS (330) and the MSI (350) may be provided in the same physical server or distributed among multiple servers.

In the example of FIG. 3, the MIS service (330) includes a new word monitor (331). The new word monitor (331) may automatically detect new words that are added to a language node (334), which may correspond to a conventional dictionary in a particular language. For example, the word “cat” may be detected as a new word added to the English language node. The word is stored as new word as new word data (333) by the new word monitor (331). For example, the new word data (331) may indicate that “cat” has been added to the English language node by the entry <en:“cat”>. The new word monitor (331) may also receive new word data from the MSI (350) when the MSI (350) receives new a string input with a word that is not recognized and stores the new word data as new word data (333). The new word monitor (331) may also receive a direct input of new word data (333) from, for example, a user. Upon detection of a new word, the new word monitor (331) initiates a new transaction in the dictionary ledger (307) with the new word data (333). The new word monitor (331) further includes a broadcast agent (332) that, upon receiving or detecting the new word, transmits the new word data (333) to the language nodes of other languages for interpretation.

In the example of FIG. 3, the MIS service (330) includes one or more language nodes (334). Each language node (334) corresponds to a language (e.g., English, Spanish, French, etc.) and includes words and their translations into other languages. For example, the English language node may have an entry for the word “dog” and its translation into Spanish, French, etc. The Spanish language node may have the entry for “perro” and its translation into English, French, etc. The French language node may have the word “chien” and its translation into English, Spanish, etc. The different language nodes (334) each corresponding to a particular language may be comprised in the same instance of the MIM (310) or in different instances of the MIM (310). That is, an instance of the MIM (310) that includes the English language node (334) may reside on a server that is different from an instance of the MIM (310) that includes the Spanish language node (334). When new word data (333) is detected by the new word monitor (331), a natural language processor (NLP) (335) of the language node (334) may suggest an interpretation of the new word in one or more languages, which is added to the dictionary ledger (307). When new word data (333) is broadcast by the broadcast agent (332) to each language node (334) in a particular different language, each language node (334) adds its interpretation of the new word to the entry for the new word in the dictionary ledger (307). When a second language node (334) receives new word data (333) from the broadcast agent (332) of a first language node (334), the second language node (334) corresponding to a particular language adds the interpretation of the new word in the particular language to the dictionary ledger (307). If an interpretation of the new word in the particular language has already been added, an interpreted word verification module (336) of the second language node (334) verifies the interpretation of the new word and/or corrects the interpretation of the new word in that particular language. Once interpretations of the new word have been added to the entry in the dictionary ledger (307), a synchronization engine (337) of the language node (334) synchronizes the interpretations in the dictionary ledger (307) with those maintained by the language node (334).

For further explanation, FIG. 4 illustrates a non-limiting example of the introduction of a new word. FIG. 4 depicts an English language node (434 a), a Spanish language node (434 b), a German language node (434 d), a French language node (434 c), and a Chinese language node (434 e), all of which are similarly configured as the language node (334) of FIG. 3. In FIG. 4, consider that new word data (333) for a new word “cat” has been added to the English language node (434 a) and/or received from the MSI service (350). The new word monitor (331) detects the new word and the broadcast agent (332) transmits the new word data (333) to the Spanish language node (434 b), the German language node (434 c), the French language node (434 e), and the Chinese language node (434 e) for interpretation into those particular languages. Further, the English language node (434 a) creates a block (401) in the distributed dictionary ledger (307) corresponding to the English word “cat.” Each language node (434 b-e) then adds the corresponding interpretation in that language to the block (401) or a subsequent block (403) in the dictionary ledger (307) indicating the English word “cat” and its interpreted pairs. For example, the Spanish language node (434 b) adds “gato,” the German language node (434 c) adds “katze,” the French language node (434 e) adds “chat,” and the Chinese language node (434 e) adds “mao” to the block (403) as interpretations of the new word “cat” in the block (401). The new word “cat” and its interpretations may then be synchronized among the language nodes (434 a-e) by propagating the entries in dictionary ledger (307) to each language node (434 a-e).

Returning to the example of FIG. 3, the MIM (310) may also include an administration module (340) for managing settings of the MIM (310). The administration module (340) may include a service profile (341) defining the SaaS parameters for services provided by the MIM (310), a language list (342) corresponding to languages for which the MIM (310) may provide interpretation service, and one or more user profiles (343) of users of the MIM (310) and their corresponding primary language.

In the example of FIG. 3, the MSI service (350) includes an MSI receiver (351) for receiving interpretation requests from a multilingual interpretation client (MIC) (510) (see FIG. 5), the interpretation request including a source language, a target language of the receiving client (510), and a string to be interpreted into the target language. The MSI service (350) also includes an MSI assigner (352) that assigns the request to an interpreting module (354) of the MSI service (350) based on the source language indicated in the request. For example, if the source language is English, the MSI assigner (352) assigns the request to an interpreting module that interprets English source words into other languages. The interpreting module (354) further includes a receiver-preferred language detector (355) that identifies a target language from the request and/or identifies a target language from the language list (342) corresponding to a primary language of a user defined in the user profile data (343). The interpreting module (354) then accesses the dictionary ledger (307) based on the identified source language and the identified receiver-preferred language, and a multilingual interpretation deliverer (356) provides the requested interpretation to the MIC (510). If a translation of the word is not recognized by the interpreting module (354), the MSI service (350) provides the word to the MIS service (330) for interpretation.

For further explanation, FIG. 5 sets forth a block diagram of an exemplary multilingual simultaneous interpretation client configured for multilingual simultaneous interpretation using a distributed ledger according to embodiments of the present invention that includes the multilingual interpretation client (MIC) (510), a module of computer program instructions for requesting multilingual interpretations from the multilingual simultaneous interpretation (MSI) service (350). The MIC (510) includes a language detector (513) that detects the language of an input word or phrase (i.e., a source language). The input word or phrase may be a text input or may be speech that is converted to text by a speech-to-text converter (514). The MIC (510) further includes a multilingual interpretation requestor (511) that formats the input word or phrase and source language into a request and sends the request for interpretation into one or more target languages to the MSI (350). For example, the request may be sent using an API provided by the MSI (350). The MIC (510) further includes a multilingual interpretation receiver (512) that receives the multilingual interpretation into one or more target languages from the MSI (350) and delivers the interpreted word or phrase to one or more recipients in their native language, for example, as a text output or as a speech output generated by a text-to-speech converter (515). For example, when word “dog” is spoken by a speaker, the speech-to-text generator (514) converts the spoken word “dog” to a text input, and the language detector (513) determines the source language to be English. The multilingual interpretation requestor (511) generates a request with the source language, target language(s), and input string and transmits the request to the MSI (350). The multilingual interpretation receiver (512) receives a reply from the MSI (350) that includes the Spanish interpretation “perro” and the French interpretation “chien” and delivers the interpretations, respectively, to a Spanish speaking audience member and a French speaking audience member.

For further explanation, FIG. 6 sets forth a flow chart illustrating an exemplary method for multilingual simultaneous interpretation using a distributed ledger according to embodiments of the present invention that includes determining (610), by a multilingual interpretation server, that a new word has been added to a first language node, the first language node corresponding to a first language. Determining (610), by a multilingual interpretation server, that a new word has been added to a first language node, the first language node corresponding to a first language may be carried out by the new word monitor (331) in the MIS (330) of the MIM (310) determining that a new word has been added to a first language node (334). For example, the new word monitor (331) may detect that a new word has been added to an English language node (334) by determining that a new word has been added to a dictionary of a particular language published by a dictionary publisher, by detecting a word received by the MSI (330) in a source language is not recognized in a shared dictionary ledger (307), or through direct input of a new word into the language node (334). Continuing a previous example, if the new word “cat” is added to an English language dictionary published by an dictionary publisher, or that a request for interpretation of the word “cat” from English to another language is received by the MSI (350) and the word “cat” is not present in the dictionary ledger (307), the new word monitor (331) determines that a new word has been added to the English language node (334).

The method of FIG. 6 also includes broadcasting (620), to a plurality of other language nodes, a request to translate the new word, each of the plurality of other language nodes corresponding to a different language. Broadcasting (620), to a plurality of other language nodes, a request to translate the new word, each of the plurality of other language nodes corresponding to a different language may be carried out by the broadcast agent (332) transmitting new word data (333) to a plurality of language nodes (334) corresponding to a plurality of different languages with a request that each language node (334) corresponding to a particular language interpret the new word data (333) into an equivalent in the particular language. Continuing a previous example, the broadcast agent (332), upon the new word monitor (331) detecting that the new word “cat” has been added to the English language node (434 a), transmits a request for interpretation of the word cat to the Spanish language node (434 b), the German language node (434 c), the French language node (434 e), and the Chinese language node (434 e).

The method of FIG. 6 also includes interpreting (630), by each of the plurality of language nodes, the new word into a particular language. Interpreting (630), by each of the plurality of language nodes, the new word into a particular language may be carried out by each language node (334) in a particular language interpreting the new word data (333) in the source language into an equivalent word in the particular language. For example, each language node (334) may use natural language processing (NLP) native to the particular language for determining an interpretation of the new word data (333) (e.g., by cross-referencing or correlating definitions in different languages), may determine that an equivalent word for the new word data (333) already exists in the language node (334) for the particular language, or may obtain an interpretation of the new word data (333) from an external source (e.g., from a user, an administrator, or through crowd-sourcing). Continuing the previous example, the Spanish language node (434 b) may receive the new word data (333) containing the English word “cat” and interpret the new word to be “gato” in Spanish.

The method of FIG. 6 also includes adding (640) the new word and one or more interpretations of the new word to an entry in a dictionary ledger. Adding (640) the new word and one or more interpretations of the new word to an entry in a dictionary ledger may be carried out by each language node (334) adding the interpreted word to a block in the dictionary ledger (307) that corresponds to the new word. The dictionary ledger (307) is local instance of a distributed blockchain data structure shared by the first language node and the plurality of other language nodes. For example, each language node (334) in particular language may add a corresponding interpretation of the new word to a block corresponding to the new word or each language node (334) may add a corresponding source:target language pair to a block corresponding to the new word or a subsequent block. Continuing the previous example, a new block (401) may be created in the dictionary ledger (307) for the new English word “cat” from the English language node (434 a). To the block (401), the Spanish language node (434 b) adds “gato,” the German language node (434 c) adds “katze,” the French language node (434 e) adds “chat,” and the Chinese language node (434 e) adds “mao.” Alternatively and additionally, the Spanish language node (434 b) may add the English: Spanish pair “cat”:“gato” to a subsequent block (403), and so on for other language nodes. The dictionary ledger (307) may then be used to provide consistent interpretations of the new word, and the various language nodes (334) in each language may synchronize interpretations of the new word with the dictionary ledger (307) to quickly propagate the addition of the new word. Each language node (334) corresponding to a particular language may add its interpretation to a local instance of a shared blockchain dictionary ledger (307), which is then synchronized with the instance of the shared blockchain dictionary ledger (307) that is local to the first language node (334). Thus, the MIM (310) may receive the interpretations added by other language nodes (334) via the shared dictionary ledger (307).

For further explanation, FIG. 7 sets forth a flow chart illustrating a further exemplary method for multilingual simultaneous interpretation using a distributed ledger according to embodiments of the present invention. The method of FIG. 7 is like the method of FIG. 6 in that the method of FIG. 7 also includes determining (610), by a multilingual interpretation server, that a new word has been added to a first language node, the first language node corresponding to a first language, broadcasting (620), to a plurality of other language nodes, a request to translate the new word, each of the plurality of other language nodes corresponding to a different language, interpreting (630), by each of the plurality of language nodes, the new word into a particular language, and adding (640) the new word and one or more interpretations of the new word to an entry in a dictionary ledger.

The method of FIG. 7 differs from the method of FIG. 6 in that the method of FIG. 7 further includes synchronizing (710) the first language node with the interpretations of the new word in the dictionary ledger. Synchronizing (710) the first language node with the interpretations of the new word in the dictionary ledger may be carried out by the synchronization engine (337) of the language node (334) synchronizing the interpretations of the new word in the dictionary ledger (307) with interpretations that are maintained in the language node (334). For example, after each language node corresponding to a particular language adds an interpretation of the new word to the dictionary ledger (307), those interpretations in the various different languages are propagated to the language node (334) corresponding to the first language. Continuing a previous example, the first language node (334) may be the English language node (434 a) that maintains interpretations of words in the English language in a plurality of different languages. When a new word “cat” is added to the English language node (434 a), other language nodes (434 b-e) add corresponding interpretations of “cat” to the dictionary ledger (307) as previously described. The interpretations added to the dictionary ledger may then be propagated to the English language node (434 a) to synchronize the English language node (434 a) with the dictionary ledger (307).

For further explanation, FIG. 8 sets forth a flow chart illustrating a further exemplary method for multilingual simultaneous interpretation using a distributed ledger according to embodiments of the present invention. The method of FIG. 8 is like the method of FIG. 6 in that the method of FIG. 8 also includes determining (610), by a multilingual interpretation server, that a new word has been added to a first language node, the first language node corresponding to a first language, broadcasting (620), to a plurality of other language nodes, a request to translate the new word, each of the plurality of other language nodes corresponding to a different language, interpreting (630), by each of the plurality of language nodes, the new word into a particular language, and adding (640) the new word and one or more interpretations of the new word to an entry in a dictionary ledger.

The method of FIG. 8 differs from the method of FIG. 6 in that determining (610), by the multilingual interpretation server, that the new word has been added to the first language node, the first language node corresponding to the first language includes determining (810) whether the new word in the first language exists in the dictionary ledger. Determining (810) whether the new word in the first language exists in the dictionary ledger may be carried out by the MSI service (350) receiving a request to interpret a source word in a source language and determining that the source word in the source language does not exist in the dictionary ledger (307). Continuing the example of FIG. 4, the MSI service (350) may receive a request to interpret the word “cat” from English to a target language. The MSI service (350) may attempt to find the source word “cat” in the dictionary ledger (307) but does not find it. The MSI service (350) may then notify the MIS service (330) that a new word “cat” has been added to the English language node (434 a) and interpretation into target languages is requested.

The method of FIG. 8 also differs from the method of FIG. 6 in that determining (610), by the multilingual interpretation server, that the new word has been added to the first language node, the first language node corresponding to the first language further includes creating (820) a new entry in the dictionary ledger for the new word in the first language. Creating (820) the new entry in the dictionary ledger for the new word in the first language may be carried out by the MIS service (330) creating a new block in the dictionary ledger (307) for the new word. Continuing the example of FIG. 4, the MIS service (330) creates block (401) in the dictionary ledger (307) for the new word “cat.”

For further explanation, FIG. 9 sets forth a flow chart illustrating a further exemplary method for multilingual simultaneous interpretation using a distributed ledger according to embodiments of the present invention. The method of FIG. 9 is like the method of FIG. 6 in that the method of FIG. 9 also includes determining (610), by a multilingual interpretation server, that a new word has been added to a first language node, the first language node corresponding to a first language, broadcasting (620), to a plurality of other language nodes, a request to translate the new word, each of the plurality of other language nodes corresponding to a different language, interpreting (630), by each of the plurality of language nodes, the new word into a particular language, and adding (640) the new word and one or more interpretations of the new word to an entry in a dictionary ledger.

The method of FIG. 9 differs from the method of FIG. 6 in that the method of FIG. 9 also includes receiving (910), from a client, a request to interpret a string in a source language to a plurality of target languages. Receiving (910), from the client, the request to interpret the string in the source language to a plurality of target languages may be carried out by the MSI receiver (351) of the MSI service (350) receiving a request for a multilingual interpretation of a source word in a source language from the MIC (510). In an embodiment, the request identifies the plurality of target languages. In another embodiment, the plurality of languages are identified from the receiver-preferred language detector (355), the user profile data (343) and/or the language list (342). For example, the MSI receiver (351) may receive a request with a header indicating the source language and a payload indicating the source word, and may also include in the header the plurality of target languages.

The method of FIG. 9 also includes generating (920) a simultaneous multilingual interpretation of the string in the plurality of target languages. Generating (920) a simultaneous multilingual interpretation of the string in the plurality of target languages may be carried out by the MSI service (350) interpreting the source word into each of the plurality of target languages using the dictionary ledger (307). For example, a source word in English is interpreted into Spanish, French, etc. by the MSI (350) identifying the source word and the corresponding interpretations in the target languages from in the dictionary ledger (307). The MSI assigner (352) may assign the request to a plurality of interpreting modules (354) corresponding to the plurality of target languages or all languages identified in the language list (342). Each interpreting module (354) generates an interpretation of the string into its corresponding language from the dictionary ledger (307).

The method of FIG. 9 also includes sending (930), to the client, the multilingual interpretation of the string in the plurality of target languages. Sending (930), to the client, the multilingual interpretation of the string in the plurality of target languages may be carried out by the multilingual interpretations deliverer (356) compiling the interpretations generated by each interpreting module (354) into a multilingual interpretation and delivering, collectively, each interpretation of the source word into the plurality of target languages to the MIC (510). For example, an interpretation of the source word into Spanish, French, etc. is collectively delivered to the MIC (510).

For further explanation, FIG. 10 sets forth a flow chart illustrating a further exemplary method for multilingual simultaneous interpretation using a distributed ledger according to embodiments of the present invention. The method of FIG. 10 is like the method of FIG. 6 in that the method of FIG. 10 also includes determining (610), by a multilingual interpretation server, that a new word has been added to a first language node, the first language node corresponding to a first language, broadcasting (620), to a plurality of other language nodes, a request to translate the new word, each of the plurality of other language nodes corresponding to a different language, interpreting (630), by each of the plurality of language nodes, the new word into a particular language, and adding (640) the new word and one or more interpretations of the new word to an entry in a dictionary ledger.

The method of FIG. 10 differs from the method of FIG. 6 in that the method of FIG. 10 also includes providing (1010) a multilingual interpretation client application, wherein the multilingual interpretation client application is configured to request (1020) a simultaneous multilingual interpretation of a string, receive (1030) the simultaneous multilingual interpretation, and deliver (1040), to each audience member of a plurality of audience members, an interpretation from the multilingual interpretation that corresponds to a language of the audience member. Providing (1010) a multilingual interpretation client application may be carried out by the MIM (310) providing the MIC (510) as a downloadable application to a client device. Requesting (1020) a simultaneous multilingual interpretation of a string may be carried out by the MIC (510), using an API of the MIM (310) defined in the MIC (350), providing a source language and a source word for interpretation into a plurality of target languages in a request to the MSI (350). Receiving (1030) the simultaneous multilingual interpretation may be carried out by the MIC (510) receiving simultaneously receiving the interpretations of the source word in the target languages from the MSI (350). Delivering (1040), to each audience member of a plurality of audience members, an interpretation from the multilingual interpretation that corresponds to a language of the audience member may be carried out by the MIC (350) identifying an audience member user and the primary language of the audience member user from the user profile data (343) and sending each audience member user an interpretation of the source word corresponding to their primary language.

In view of the explanations set forth above, readers will recognize that the benefits of multilingual simultaneous interpretation using a distributed ledger according to embodiments of the present invention include improvements to machine interpretation of a source language to a several different target languages, increased capability in propagating a new word in a source language to other languages, enhanced consistency among dictionary interpretations in different languages using a shared distributed dictionary leger, and increased speed in simultaneous machine interpretations of a source language to several different target languages using a using a shared distributed dictionary ledger.
